Question #1
you are writing a report that needs to compute the sum of multipul columns and display the result.
The number of columns to sum varies from report to report but does not exceed five.
Which two options can you use to implement this requirement? (choose two)
- A . Develop a SQL function that sums two columns. Recursively apply this function as needed.
- B . implement a declare expression to sum the values and store the result as an additional property.
- C . construct the report to group by the columns to be summed followed by a column that uses SUM.
- D . Develop separate SQL functions for summing two through five columns. use the appropriate function.
Correct Answer: B C
B C
Explanation:
Declare Expression: Use a Declare Expression to calculate the sum of the columns and store the result in an additional property. This ensures that the sum is always updated when any of the contributing values change.
Report Configuration: Configure the report to group by the columns to be summed and use the SUM function for aggregation. This approach leverages Pega’s reporting capabilities to dynamically compute and display the sum based on the selected columns.

Question #2
You isolated the problem to node 1 of the cluster. You see node 1 goes down shortly after 3:00 p.m. every day with an out-of-memory error.
Which two alerts typically precede this condition? (choose two)
- A . PEGA0004 CQuantity of data received by database query exceeds limit
- B . PEGA0001 C HTTP interaction time exceeds limit
- C . PEGA00017 C Cache exceeds limit
- D . PEGA0002 C Connect operation time exceeds limit
Correct Answer: AC
AC
Explanation:
Identifying and resolving out-of-memory errors in a cluster node involves understanding the alerts that typically precede such conditions.
PEGA0004 C Quantity of data received by database query exceeds limit (Answer A):
This alert indicates that a database query is returning more data than expected, which can lead to memory issues as the system tries to handle large data sets.
Reference: Pega documentation details that PEGA0004 alerts help identify inefficient database queries that could lead to performance degradation and memory issues. PEGA00017 C Cache exceeds limit (Answer C):
This alert indicates that the cache has exceeded its predefined limit, which can cause memory overflows and out-of-memory errors.
Reference: According to Pega performance tuning guidelines, monitoring cache limits and adjusting cache settings can prevent out-of-memory conditions.

Question #4
Which two approaches can you take to facilitating Mashup interface development in App Studio? (Choose Two)
- A . Within a Development-only application built on the Production application, define a case type that pauses at an assignment. The modal flow action displayed for that case should have the same data class as a Mashup interface that uses the Display a page option.
- B . In the pyDefault Data Transform for a case, set pxThread.isWebMashup to True by using an Application Setting. App Studio users then see the same views that are displayed by a Mashup interface when it is configured to use the Create a case option.
- C . Use associated privilege visibility conditions. At design time, an App Studio user is able to view and configure sections that are only shown to external personas.

Question #6
A local ferry service offers a passenger boat trip that travels from Port A to Port B, and then back again, once a day. Passengers can book tickets using an app, and they often try to make last-minute reservations for the outbound trip. The ferry service wants their app to place a passenger on a waiting list for the first trip, while guaranteeing them a reservation for the second trip.
Which two case design patterns apply to this scenario? (Choose Two)
- A . Limited Availability and Concurrency
- B . Parallel Case Processing
- C . Divide and Conquer
- D . Data Instance First
Correct Answer: A, C
A, C
Explanation:
Limited Availability and Concurrency: This pattern handles situations where resources (like ferry seats) are limited, and concurrency needs to be managed to ensure fair allocation.
Divide and Conquer: This pattern involves breaking down a case into sub-cases or steps, such as managing bookings for both the outbound and return trips separately.

Question #7
A form listing nearby restaurants has four columns:
– Restaurant name
– Restaurant location
– Thumbnail image of the seating area
– Make reservation (check box)
You want to ensure that users have the information they need to make a reservation regardless of screen size. When viewed on a small screen, you do not need to display images.
What three configuration steps do you take to support this requirement? (Choose three.)
- A . Set the importance of the Make reservation column to Primary.
- B . Set the importance of the Restaurant name column to Primary.
- C . Set the importance of the image column to Other.
- D . Set the importance of the image column to Secondary.
- E . Set the importance of the Restaurant location and Make reservation columns to Secondary.
- F . Set the importance of the Restaurant name and Make reservation columns to Primary.
Correct Answer: B, D, E
B, D, E
Explanation:
Column Importance: The importance setting helps define which columns are displayed on smaller screens. "Primary" ensures the column is always visible, "Secondary" is shown if there is enough space, and "Other" is hidden on smaller screens.
Restaurant Name as Primary: Setting the restaurant name to primary ensures it is always visible, as it is crucial information for making a reservation.
Image Column as Other: Setting the image column to "Other" hides it on small screens, which is acceptable as images are non-essential compared to textual information.
Location and Reservation as Secondary: These columns are set to secondary, ensuring they are visible on medium to large screens but can be hidden on smaller screens if space is limited.
Reference: Pega guidelines recommend using the importance settings to manage the visibility of columns in responsive layouts, ensuring critical information is prioritized (Pega Platform 8.7 Documentation, User Interface – Column Settings).

Question #8
Table a contains customer information. Table B contains complaints submitted by customers. Table C contains positive feedback submitted by customer.
You are tasked to write a report that list all rows in Table A where, per customer, the number of rows in Table B related to Table A are greater than the number of rows in Table C related to table A.
Which method creates the report that executes with the best performance?
- A . Define two subreports: one that counts rows in Table B relative to Table A, and on that counts the rows in table C relative to Table A. Only include rows in the main. Report against table A where the table B count is greater that the Table C count.
- B . Join table A to Table B and C using include all rows in this class. Count the Join column from both Table B and Table C. Only include rows where the first count is greater than the second.
- C . Join table A to Table B and C using include all rows in join class. Count the Join column from both Table B and Table C. Only include rows where the first count is greater than the second.
- D . Define two subreports, one where table B users ”Do not Join”, and one where Table C users ”Do not Join”, In the main report count the rows from each subpreport, then only include rows where the count from the Table B subreport than the count from the Table C subreport.
Correct Answer: A
A
Explanation:
To create a report that lists all rows in Table A where the number of related rows in Table B is greater than in Table C per customer, define two subreports. One subreport counts rows in Table B relative to Table A, and the other counts rows in Table C relative to Table A. In the main report, include only rows from Table A where the Table B count is greater than the Table C count. This method ensures optimal performance by avoiding complex joins.
